The work required to pump all of the olive oil to the rim of the tank is equal to the weight of the olive oil multiplied by height of the tank.

Work = 41 lb/ft3 x (height of the tank)

For example, if the height of the tank is 6 ft,

Work = 41 lb/ft3 x 6 ft = 246 lb-ft

The work required to pump all of the olive oil to the rim of the tank is equal to the weight of the olive oil multiplied by the height of the tank.

The work required to pump all of the olive oil to the rim of the tank is equal to the weight of the olive oil (which is typically measured in pounds per cubic foot) multiplied by the height of the tank in feet. Thus, the work required can be expressed as: Work = (Weight of olive oil) x (Height of tank in feet). For example, if the olive oil has a weight of 41 pounds per cubic foot and the height of the tank is 6 feet, the work required to pump the olive oil to the rim of the tank would be 246 lb-ft (41 lb/ft3 x 6 ft).

If McKenzie pays $150 per month, she will have paid a total of $92.832 in interest when she pays off her credit card. This is $36.224 more than she would have paid if she had paid $250 per month.

APR stands for Annual Percentage Rate, which is the interest rate associated with a loan, credit card, or other type of borrowing. It is expressed as a percentage and is typically higher than the interest rate because it includes additional costs associated with the loan such as origination fees, processing fees, and other costs.

Part A:

To calculate how long it will take McKenzie to pay off her credit card, we need to use the formula:

T = (B x i) / P

Where T is the total number of payments, B is the initial balance, i is the interest rate (in decimal form) and P is the amount of the payments.

In this case, B = 936, i = 0.01396 (13.96% expressed as a decimal) and P = 250. So, substituting these values into the formula, we get:

T = (936 x 0.01396) / 250

T = 3.784

Since payments are made monthly, we can round this to 4 payments. Therefore, it will take McKenzie 4 months to pay off her credit card if she makes payments of $250 per month.

Part B:

To calculate the amount of interest McKenzie will have paid when she pays off her credit card, we can use the formula:

I = B x i x T

Where I is the total amount of interest paid, B is the initial balance, i is the interest rate (in decimal form) and T is the total number of payments.

In this case, B = 936, i = 0.01396 and T = 4 (since we calculated this in Part A). So, substituting these values into the formula, we get:

I = 936 x 0.01396 x 4

I = 56.608

Therefore, McKenzie will have paid a total of $56.608 in interest when she pays off her credit card.

Part C:

To calculate how much more interest McKenzie will pay if she only pays $150 per month, we first need to calculate how long it will take her to pay off the credit card using this lower payment amount.

Using the same formula from Part A, we get:

T = (936 x 0.01396) / 150

T = 6.576

Since payments are made monthly, we can round this to 7 payments. Therefore, it will take McKenzie 7 months to pay off her credit card if she makes payments of $150 per month.

Now, to calculate the amount of interest McKenzie will have paid if she pays $150 per month, we can use the same formula from Part B:

I = B x i x T

Where I is the total amount of interest paid, B is the initial balance, i is the interest rate (in decimal form) and T is the total number of payments.

In this case, B = 936, i = 0.01396 and T = 7. So, substituting these values into the formula, we get:

I = 936 x 0.01396 x 7

I = 92.832

Therefore, if McKenzie pays $150 per month, she will have paid a total of $92.832 in interest when she pays off her credit card. This is $36.224 more than she would have paid if she had paid $250 per month.

The letter represented by the star symbol is 1.

We can start by using the rules of arithmetic. Since each symbol represents a different digit, we can represent the symbols with the numbers 0 to 9. Then we can write the equation as an algebraic expression and solve for the star symbol.

Let's assign the value of the letter represented by the star symbol to x.

A + B = 10x + x = 11x

We know that the maximum value for the result of the addition (C) is 18 (9 + 9) and that the maximum value for 11x is 990 (90 * 11), so x cannot be greater than 9.

Let's try the lowest value for x, which is 0.

A + B = 10 * 0 + 0 = 0

Since 0 cannot be a digit in A or B, x cannot be 0.

Let's try the next value for x, which is 1.

A + B = 10 * 1 + 1 = 11

Since 11 is a valid result of the addition, x = 1 is a solution.

Therefore, the letter represented by the star symbol is 1.

Answer:

Step-by-step explanation:

To find the cost of a 33-minute taxi ride, we first need to determine the cost per minute of the taxi ride. We can do this by dividing the cost of a 14-mile taxi ride ($11.20) by the time it took (16 minutes):

$11.20 ÷ 16 minutes = $0.70 per minute

Now that we know the cost per minute, we can find the cost of a 33-minute taxi ride by multiplying the cost per minute by 33:

$0.70 x 33 minutes = $23.10

So a 33-minute taxi ride at this vacation spot would cost $23.10.

The General Multiplication Rule in probability states that the probability of the intersection (occurrence) of two events, A and B, is equal to the product of their individual probabilities. The formula can be written as follows:

p(A and B) = p(A) * p(B | A)

where p(A) represents the probability of event A occurring, and p(B | A) represents the probability of event B occurring given that event A has already occurred.

The formula reflects the idea that the probability of both events occurring is equal to the probability of one event occurring, multiplied by the probability of the other event occurring given that the first event has already happened.

For example, let's say we have two events: "rolling a 6 on a dice" (A) and "choosing a spade from a deck of cards" (B). The probability of rolling a 6 on a dice is 1/6, and the probability of choosing a spade given that a 6 was rolled is 13/52. Using the general multiplication rule, the probability of both events occurring would be (1/6) * (13/52) = 13/312.

In summary, the general multiplication rule is a fundamental concept in probability that helps us calculate the probability of the intersection of two events.

Equation can be used to represent relationships between variables and to solve problems. They are written using an equal sign (=) and can include numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

To make y the subject of the equation x = √((y-1)/(y+1)),

x = √[(y-1)/(y+1)]

we can square both sides:

x² = (y-1)/(y+1)

Next, we can multiply both sides by (y+1) to get rid of the fraction:

x² × (y+1) = y-1

x²y + x² = y - 1

Rearranging the terms:

x² + 1 = y - x²y

x² + 1 = y(1 - x²)

Divide both side by (1-x²) we get

y = (x²+1)/(1-x²)

So, y is the subject of the equation is y = (x²+1)/(1-x²)

This is a normal distribution problem with

Mean = μ =

Standard deviation = o = .

A) Probability that a randomly selected medical

student who took the test had a total score that

was less than 484 = P(x < 484)

We first normalize or standardize 484

The standardized score for any value is the value

minus the mean then divided by the standard

deviation.

z = (x-μ)/o = (484 - 500)/10.4 = - 1.54

To determine the required probability

P(x < 484) = P(z < -1.54)

We'll use data from the normal distribution table

for these probabilities

P(x < 484) = P(z < -1.54) = 0.06178

We normalize or standardize 504 and 516

For 504

z = (x -μ)/σ = (504 500)/10.4 = 0.38

For 516

z = (x - μ)/σ = (516-500)/10.4 = 1.54

To determine the required probability

P(504 ≤ x ≤ 516) = P(0.38 ≤ Z ≤ 1.54)

We'll use data from the normal distribution table

for these probabilities

P(504 ≤ x ≤ 516) = P(0.38 ≤ Z ≤1.54)

The probability that a randomly selected medical student who took the test had a total score that was less than 480 is 0.49, which means that approximately 49% of medical students had a score lower than 480.

To calculate the probability that a randomly selected medical student who took the test had a total score that was less than 480, we need to start by looking at the data given. In this case, the data tells us that the mean score was 500 and the standard deviation was 50. This means that the scores are normally distributed, which means that the probability of finding a score lower than 480 can be calculated using the normal distribution formula. We can use this formula to calculate the area under the curve (or probability) below the score of 480. The result of this calculation is 0.49, which means that approximately 49% of medical students had a score lower than 480.
